Find the equation of the line connecting (0, 5) and (-2, 0).
As we go from the first point to the second, x decreases by 2 and y decreases by 5. Thus, the slope of this line is m = rise / run = -5/(-2), or 5/2.
Starting with the general equation of a line in slope-intercept form, y = mx + b, substitute the knowns as appropriate to determine the value of b:
y= mx + b => 5 = (5/2)(0) + b. Then b = 5, and the desired equation is
y = (5/2)x + 5.
Check this! If we subst. the coordinates of (-2,0) into this equation, is the equation true?
0 = (5/2)(-2) + 5
Yes. So, y = (5/2)x + 5 is the desired equation.
Answer:
In linear expresiion 3 is the coefficient
X will be the variable and -15 will be the constant term.
C. 3.5
You have to go to -2 on the “X axis” and find the corresponding “Y” value on the line.
Answer: 3/8ths
Step-by-step explanation: 1/8+1/8+1/8=3/8
2x+3y=12
Subtract by 2x
3y=-2x+12
Divide by 3
y=-2/3x+4
